Hi,
Is the issue specific to office programs?
As the error log indicates that you were trying to access MS word when you got the error perform clean boot and check.
Perform clean boot using the suggestions mentioned in the link mentioned below.

Note: After you check the functionality in clean boot configure Windows to use Normal startup using the step 7 suggested in the above mentioned link.
If the issue is specific to Microsoft Office program, I suggest you to post the issue in Microsoft Office forum using this link.
